Title: Driving method of injector for internal combustion engine
Inventor: ARAKAWA YOSHINOBU
IPC: F02M51/00
Filed: 1993-08-02
Abstract: PURPOSE:To provide a driving method of an injector for an internal combustion engine which can improve startability of the engine. CONSTITUTION:Power supply circuit 3 for charging an electric power supply condenser 3c by output of a power generation coil 3 provided in a power generator is provided, and driving current Ic from the electric power supply circuit 3 is flowed to the driving coil 4a of an injector when an injection command signal Vjo is given. Generation of the injection command signal Vjo is prevented until the necessary electric charge for driving the injector is accumulated in the electric power supply condenser 3c at the time of starting the engine as the period of prohibition of injector driving, so as to prohibit flow of the driving current Ic. The injection command signal Vjo is generated and then flow of the driving current Ic is allowed after the injector driving prohibition period is passed, and the necessary electric charge is accumulated in the electric supply condenser 3c.

Patent JP-H0946176-A (JP)
Title: Attenuator
Inventor: KASAHARA MICHIAKI
IPC: H03H11/24
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To facilitate miniaturization and the design by selecting the combination of on/off states of plural FETs to which resistors are loaded in parallel or in series so as to select the operation as a pass circuit or the operation for a T-shaped attenuator. SOLUTION: When a FET(field-effect transistor) 1 and a FET 3 are conductive and a FET 4 is nonconductive, a high frequency signal passes through the FET when the FET is conductive and the FET interrupts the high frequency signal when the FET is nonconductive. Since the FET 4 is regarded as an open end with respect to a major line tying input output terminals 6, 7 in the attenuator equivalent circuit, the entire attenuator acts like a passing circuit. When the FETs 1, 2 are nonconductive and the FET 4 is conductive, the attenuator acts like a T-shaped attenuation circuit by resistors 2a-2c in the attenuator equivalent circuit. Thus, the passing loss difference of both circuit is attenuated and even when desired attenuation is different, the matching design with circuits before and after the attenuator is easily executed.

Title: Non-contact liquid sensor type ultrasonic vortex flowmeter
Inventor: YASUMATSU AKIO
IPC: G01F1/32
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To stabilize the action of an ultrasonic vortex flowmeter and expand the measurable range of the flowmeter to a low flow velocity region by providing a protective cover which covers a conduit as a leakage preventing body. SOLUTION: A protective cover 11 which is made of stainless steel and covers a conduit 1 is provided as a leakage preventing body for preventing the leaking out of ultrasonic waves from the conduit 1. Part of the ultrasonic waves transmitted from a transmitter 4 is received by means of a receiver 5 as leakage ultrasonic waves after passing through the conduit 1. Since the cover 11 is provided, however, no rain drops, etc., come into collision with the conduit 1 and the variation of the leakage ultrasonic waves can be reduced. Therefore, the measured value of an ultrasonic vortex flowmeter does not receive any adverse influence even when the flowmeter is exposed to rainfalls, sprayed water, etc.  In addition, the adverse influence does not appear remarkably as fluctuations, erroneous outputs, etc., when the flow velocity of a fluid is low or the flow rate of the fluid is zero at which the modulation by a Karman vortex becomes smaller.

Title: Variable power optical device for copying machine
Inventor: MIURA MASAAKI
IPC: G03B27/34
Filed: 1988-08-01
Abstract: PURPOSE:To surely achieve movement of a mirror even when a moving amount is large by supporting an operation lever so as to rock, equipping a cam follower on one end, connecting it with a mirror retaining member on the other end, and arranging it so as to move the mirror retaining member following a cam member. CONSTITUTION:Relation between the shape of the cam groove 4A of a cam plate 4 and the position of the supporting point of a lever 7 is set so that displacement from the rotation center of the cam groove 4A is maximum when magnification ratio is set for that of unmagnification. In addition, the cam groove 4A is set so as to approach the rotation center when the lever is moved to an enlarging side or a reducing side. As a result, a mirror holder 2 is moved by a large amount for the rotation angle of the cam plate 4 especially when the lever is moved from an unmagnified position to the enlarging side. Even when additional force is required, an identical torque can be used as a strong driving force for movement, because the cam groove 4A approaches the rotation center.

Title: Printer and printing system
Inventor: NODA KATSUYUKI
IPC: G06F3/12
Filed: 1991-07-31
Abstract: PURPOSE:To shorten the printing time by printing a print image displayed on a screen on a printing form as it is. CONSTITUTION:Image data 2 which are outputted as screen data by the data recognition of a computer 1 are transferred to the printer 3. The printer 3 places the copy screen of a print image display part 4 at an original setting position on the top surface of a copying part 5, which regards the print image displayed on the copy screen as original paper to print a copy on the printing form. In this case, as the process of the copy printing of the print image on the printing form by the copying part 5 becomes faster and faster, the printing time is made closer to the time required by the computer 1 to display the image data 2 as screen information. Therefore, the printing throughput of the printer 3 is improved as the screen display throughput of the computer 1 is improved.
